In earlier posts, I've talked about finding ancestors under the mother's maiden name. Another way you can try finding an ancestor's parents' names, look for the siblings and see if you can find them by searching for their records.
I don't know if I've stressed this before but it's a good idea to get your school records. I got mine from my school district for $1.00. It was fun to see if my memories of my grades matched what was in the records. I can brag about my good grades in my life story.
